Mathematical Data Modelling of Tsunami from Makran Subducion zone and Its Impact on Lakshadweep Islands and west coasat of India

Abstract

quotOne of the most destructive and devastating tsunami in the Arabian sea is the 1945 Makran newlinetsunami which occurred on November 27th in the Makran Subduction Zone (MSZ) because of an newlineearthquake having 8.1 ( ) magnitude. The epicentre of this particular seismic activity is at newline63.48O E, 25.15O N about 100 km west of Karachi, off the coastal region of Makran along the newlinenorthern part of Arabian Sea and roughly 87 km southern - south western part of Baluchistan, newlinePakistan. It is the one and only well documented tsunami for which information regarding the newlinerun-up heights along the coastal regions and magnitude of earthquake is available in literature. In newlinemy thesis an estimation of the impact of tsunamigenic earthquakes are carried out for the Islands newlineof Lakshadweep and the western coastal cities / areas of India. Moreover this study is focused in newlineestimating the protection that Lakshadweep Islands are providing to the west coast of India by newlineusing a mathematical model and appropriate sets of bathymetry and elevation data. Also GIS newline(Geographical Information System) is used to study the tsunami arrival time analysis.quot newline newline
